Is it possible or how to make a drive with data to a mirrored drive by adding another drive

[MKumar Nagappa]

hp g4 ml350

hp 641 raid controller

array a - 36gb x 2 mirrored set - C partition

then i have a single 146gb drive just a drive which is D drive with live data on the same controller card.

Now can i add another 146gb drive and then make this second drive , that is along with
first 146gb drive a mirror pair without losing the existing data on the 1st 146gb drive.

thank you

I imagine you have an array b for your current 146GB drive so, yes, you can add the 2nd 146GB to your array b and then in the ACU you specify the mirror you save the config and it will start building the mirror. You won't lose your existing data
